    Broke: Whales are fish because they look like other fish

    Woke: Whales aren’t fish because they’re in the class Mammalia, not Pisces

    Bespoke: Whales are fish any monophyletic group that encompasses all the fishes must also include the clade Tetrapoda

    Artichoke: Whales aren’t fish because fishes are a paraphyletic group that includes the entire clade Vertebrata at the exclusion of the clade Tetrapoda.

    Stick and Poke: Whales are fish because they’ve developed the same bodyplan and are in the same ecological niche as the pelagic fishes.

        I don’t know how many times I have to say this, I AM NOT A FISH! I am a regular tasty human, and frankly I’m growing real tired of these targeted attacks. You people are ridiculous. I won’t swi-STAND! Y-we stand. I won’t stand for this!

    I think a more nuanced answer is better: “Only if you believe mammals and fish are not mutually exclusive.”

      I think the even more nuanced answer is that “fish” is not a scientific category so comparing it to mammals makes no sense.

          In a break from the long tradition of grouping all fish into a single class (‘‘Pisces’’), modern phylogenetics views fish as a paraphyletic group.

          Paraphyly is a taxonomic term describing a grouping that consists of the grouping’s last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic with respect to the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and all of its descendants.

          This is in contrast to the class Mammalia which is a complete clade.

          In other words, I could make up a branch of science called foobarthology that studies Jurassic raptors, whales, and the Rock Dove, but that doesn’t mean those things are related, or a ‘true’ scientific group of their own. It just means I put them together for some other reason, either cause it’s easier for the requirements of the job, or I wanted to, or many other reasons including historical.

    No, but seriously, why did this become so common? It seems like the internet learnt a new word and is just rolling with it.

      Well, yea that. I know Hank Green likes to bring it up and he’s popular, and it’s come up with a bunch of other content creators, too. It’s fun, technically true, and enough people don’t know it yet so it’s great to bring up in the real world.

      Plus it’s super cool to explain how our eyes are built for the ocean and they had to get a special lens on top to fix it. Or how we carry the sea with us in the form of all this salty water. Or the whole swimbladder/lungs/guts thing relationship I mean they’re all quite fun, really.

      I also like explaining that octopuses are molluscs and, because we say that molluscs have one “foot”, it’d be more appropriate to say that octopuses are really just going around the world with eight funky toes and not eight arms.

        Didn’t know that octopus came from the molluscs branch. Even more surprising that they at a smart as they are.

        Never gave any thought to were they branched off, but them being advanced slugs is crazy.

          Yea it’s wild. Frickin’ love this stuff, especially when it’s all easy enough to learn and explain accurately enough for fun fact time.
